Review of safety data

Data under review for Phase II/III study


As part of the ongoing randomised controlled global trials of the coronavirus vaccine, our standard review process triggered a study pause to vaccination to allow review of safety data. This is a routine action which has to happen whenever there is a potentially unexplained illness in one of the studies, while it is investigated, ensuring we maintain the integrity of the trials. In large trials illnesses will happen by chance but must be independently reviewed to check this carefully. All routine follow-up appointments are continuing during this period. We are committed to the safety of our participants and the highest standards of conduct in our studies.
